ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive. Vinyl chloride monomer vapours are uninhibited and may form polymers in vents or flame arresters of storage tanks, resulting in blockage of vents.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE
STRICT HYGIENE!

  • INHALATION
  • Dizziness. Drowsiness. Unconsciousness.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
  • Redness. Skin burns.
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
  • Redness. Pain.
    Safety goggles, or eye protection in combination with breathing protection.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Abdominal pain. Sore throat (further see Inhalation).
    Do not eat, drink, or smoke during work. Wash hands before eating.
    Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Consult an expert! Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Fireproof. Separated from incompatible materials (see Chemical Dangers). Cool. Keep in the dark. Store only if stabilized.
    Airtight. Unbreakable packaging; put breakable packaging into closed unbreakable container. IMO: Marine Pollutant

    PHYSICAL STATE; APPEARANCE:
    VOLATILE COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:
    The vapour is heavier than air and may travel along the ground; distant ignition possible.

    CHEMICAL DANGERS:
    The substance can readily form explosive peroxides. The substance will polymerize readily due to heating or under the influence of oxygen, sunlight, copper or aluminium, with fire or explosion hazard. May explode on heating or on contact with flames. The substance decomposes on burning producing toxic and corrosive fumes (hydrogen chloride, phosgene and chlorine). Reacts violently with oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 5 ppm; 20 mg/m3 (STEL): 20 ppm; 79 mg/m3 (ACGIH 1992-1993).


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

    INHALATION RISK:
    A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes, the skin and the respiratory tract. Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. The substance may cause effects on the central nervous system.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the liver and kidneys.

    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to water organisms. In the food chain important to humans, bioaccumulation takes place, specifically in plants.
    NOTES
    Contains inhibitors (e.g. methoxyphenol). Depending on the degree of exposure, periodic medical examination is indicated. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
